I have a production Windows 2008 R2 server, and my workstation is Gentoo linux (kernel 3.12.13). I used to connect to server with rdesktop.
Now I want to restrict the windows firewall rule for rdp (built-in rule) to allow connections from certain IPs only. Firewall demands that only secure rdp connections can be restricted and gives me 4 options:
- allow the connection if it's authenticated and integrity protected
- require the connections to be encrypted
- allow the connection to use null encapsulation
- override block rules
I don't know which option is supported by my Gentoo rdesktop.
- What type should I choose?
- Should I modify rdesktop parameters and how?
